The Genitalia of the Group Geometridae of the Lepidoptera of the 

 British Islands. An Account of the Morphology of the Male 

 Clasping Organs and the Corresponding Organs of the Female. By 

 F. N. Pierce. Liverpool, F. N. Pierce, The Elms, Dingle, 1914. 

 Mr. Pierce is the author of a similar work on the Genitalia of the 

 British Noctuidae, published in 1909. The present volume consists of 

 88 pages and 48 plates. There is an introduction of 12 pages, describ- 

 ing the genitalic anatomy and the nomenclature of the parts. Then 

 follows the classification of the British Geometridae based on the 

 structure of the male and female genitalia. The genitalia of the spe- 

 cies are described as well as accurately figured. The whole work is 

 largely original and shows careful study. There can be no question 

 in regard to the wonderful aid afforded by the genitalia in systematic 

 work. This fact is now well established by the work of careful stu- 

 dents of the Lepidoptera both in Europe and .\merica. One of its 

 great values is to establish maculation and other characters between 

 species not readily separated, but now readily differentiated by an 

 examination of the sexual appendages. So far as we are aware, the 

 first studies in this line in America were made by Scudder and Bur- 

 gess in 1870, but they attracted little attention. In the future it will 

 be impossible for students to neglect this fertile held of study. — H. S.
